Title: Developing device
Inventor: MATSUDA MASANORI
IPC: G03G15/08
Filed: 1990-07-31
Abstract: PURPOSE:To replenish the uniform quantity of toner to a developing sleeve so that an image may be excellently formed, to detect that the toner is depleted and to replenish the toner so that a developing device may be smoothly operated by detecting the quantity of toner on the developing sleeve and automatically adjusting bias voltage on the developing sleeve. CONSTITUTION:The developing device 2 is provided adjacently to a photosensitive drum 1 and the toner T is replenished from the sleeve 3 to the drum 1. The bias voltage having a reverse polarity to the toner T is impressed on the sleeve 3 by a voltage adjusting means 4 and the toner T is attracted to the sleeve 3. Then, a doctor blade 5 is provided so that its tip may restrict the thickness of the toner T to form a fixed thin layer on the sleeve 3. A sensor 6 for detecting the thickness of a toner layer on the developing sleeve is disposed on the downstream side of the blade 5. When there is a little toner T on the sleeve, the bias voltage of the means 4 is made higher, the adhering quantity of the toner T on the sleeve 3 is increased, and the thickness of the toner T is adjusted and maintained to be fixed one, thereby stabilizing the density of the formed image. When the toner T is not increased even when the bias voltage is made high, the toner is replenished by judging that the toner T is depleted.

Title: Preparation of activated alumina carrier having high pore void volume
Inventor: SUENAGA HIROYASU
IPC: B01J21/04
Filed: 1985-09-13
Abstract: PURPOSE:To easily form desired fine pore distribution, by granulating hydraulic alumina, obtained by treating aluminum hydroxide having specific particle size distribution and a specific average particle size in a hot air stream at specific temp., while water is sprayed to said alumina. CONSTITUTION:Aluminum hydroxide wherein the content of particles with a particle size of 5mum or less is 80% or more and an average particle size is 0.5-5mum is thrown in a hot air stream with temp. of 400-1,200 deg.C for 0.1-10sec to form hydraulic alumina.

Title: Lead-acid battery
Inventor: ARAI TAKAYUKI
IPC: H01M10/06
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide good life performance without reducing the discharge capacity at the initial stage of charge/discharge, by forming a layer which contains lignin and carbon material absorbing the lignin on a surface of a negative electrode plate. SOLUTION: Negative electrode active material 2 on a surface of a negative electrode plate 1 contains lignin, and the lignin elutes into electrolyte from the electrode plate surface during formation of a battery jar or charge/discharge. Because the lignin in a layer 3 on the surface of the negative electrode plate 1 is absorbed into carbon material due to their mixing existence, the holding period of the lignin to the negative electrode plate 1 becomes longer, and the elution rate of the lignin from the layer 3 into electrolyte is moderated. Lignin elutes gradually from the negative electrode active material 2, but the layer 3 blocks elution passage and restrains elution of the lignin from the negative electrode active material 2. Because the layer 3 maintains its function even during charge/discharge cycle, it continues it effect all over the life period.  Thickness of the layer 3 is 0.02-0.4 when the thickness of the negative electrode plate 1 before formation of the layer 3 is set to 1.0.

IPC: B23K15/02
Filed: 1988-08-16
Abstract: PURPOSE:To improve automatic following-up accuracy by superimposing a specific % commercial frequency AC part on a bias power source circuit of an electron gun to supply it and synchronizing deflection scanning of an electron beam with commercial frequency AC. CONSTITUTION:The bias power source circuit to supply the DC bias voltage to Wehnelt 9 of the electron gun is arranged and a transformer 6, a rectifier 5, a choke 4 for smoothing and capacitors 2 and 3 are set up respectively. By this mechanism, about several tens % commercial frequency AC part is superimposed on the bias power source circuit and supplied. At this time, when synchronization 14 is executed at the peak time of a beam current, since a beam current value at the time of scanning is the same, a detected signal is made to the same size but a beam current effective value is remarkably reduced. By this method, an effect of the damage occurrence, etc., on material 12 to be welded is reduced very much. Accordingly, automatic following-up accuracy with respect to the joining line is improved.

Abstract: PURPOSE:To enable an automatic releasing of a lid without providing any trouble in an ice making operation by a method wherein the ice making device has the second engaging part for engaging with a free end rather than an engaging position by the first engaging part of the lid and further releasing the lid when the lid is released by a predetermined angle in respect to the ice making pan. CONSTITUTION:As water in an ice making pan 21 is completely frozen, the ice making pan 21 is rotated by a driving mechanism 18. At this time, an engagement between an engaging recessed part 29 of the ice making pan 21 and a claw part 27a of a sliding movement transmitting member 27 is released. At the initial stage of rotation of the ice making pan 21, a free end 22a of a groove 32 in the lid 22 is engaged with the first engagement part 34, thereby the lid 22 starts to open. As the ice making pan 21 is further rotated, the engaging part of the first engaging part 34 in respect to the lid 22 is moved toward the connection part 31, a releasing angle of the lid 22 is increased and at the same time its free end part 22a is placed from above to the second engaging part 35. As the ice making pan 21 is further rotated from this state and the lid 22 becomes the released state by a predetermined angle, the free end 22a of the lid 22 is engaged with the second engaging part 35 in place of the first engaging part 34 and released by this engagement.
